Chinese hamster ovary (CHO) cells have been widely used for producing many recombinant therapeutic proteins. Constraint‐based modeling, such as flux balance analysis (FBA) and metabolic flux analysis (MFA), has been developing rapidly for the quantification of intracellular metabolic flux distribution at a systematic level. Such methods would produce detailed maps of flows through metabolic networks, which contribute significantly to better understanding of metabolism in cells. Although these approaches have been extensively established in microbial systems, their application to mammalian cells is sparse. This review brings together the recent development of constraint‐based models and their applications in CHO cells. The further development of constraint‐based modeling approaches driven by multi‐omics datasets is discussed, and a framework of potential modeling application in cell culture engineering is proposed. Improved cell culture system understanding will enable robust developments in cell line and bioprocess engineering thus accelerating consistent process quality control in biopharmaceutical manufacturing.

Abstract The single radial immunodiffusion assay has been the accepted method for determining the potency of inactivated influenza vaccines since 1978. The world‐wide adoption of this assay for vaccine standardisation was facilitated through collaborative studies that demonstrated a high ... more
Abstract Background Whether morbidity from the 1918‐19 influenza pandemic discriminated by socioeconomic status has remained a subject of debate for 100 years. In lack of data to study this issue recent literature have hypothesized that morbidity was “socially neutral”. Objectives ... more
Smart skin that can respond to external stimuli could have important applications in medicine and robotics. Using only items found in a typical household, researchers have created multi-sensor artificial skin that's capable of sensing pressure, temperature, humidity, proximity, pH, and air ... more
Some doctors may recommend that patients with the flu take acetaminophen, or paracetemol, to relieve their symptoms; however, a new randomized clinical trial found no benefits to the over-the-counter medication in terms of fighting the influenza virus or reducing patients' temperature or ot ... more
A new study that investigated the potential of certain psychological traits for predisposing heterosexuals to have negative attitudes towards homosexual people found that psychoticism - which is present in severe psychopathological conditions but may also contribute to less severe states of ... more
